HMS Erebus and HMS Terror, 1845

Engraving showing HMS Erebus (left) and HMS Terror, pictured on the River Thames, 1845. In 1845 the British Admiralty sent two polar exploration ships, HMS Erebus and HMS Terror, to look for the Northwest passage round the northern coast of Canada. The expedition, commanded by Sir John Franklin, disappeared from view late in 1845 and none of the men were ever seen again. In fact the ships made it to the King William Island region, then got stuck in the ice. With supplies running out the surviving crew abandoned ship and headed south. However, none made it to safety and it is assumed all died from disease, exposure or starvation. From 1848 onwards a number of relief expeditions were sent to find Franklin, but it was only in 1859 that Francis Leopold McClintock was able to confirm Franklin's fate

Particle tracks

Subatomic particle tracks. Coloured bubble chamber photograph showing tracks left by subatomic particles from a particle accelerator at CERN, the European particle physics laboratory at Geneva. A bubble chamber is a container filled with liquid hydrogen which is superheated - momentarily raised above its normal boiling point by a sudden drop in pressure in the container. Any charged particle passing through the liquid in this state leaves behind a trail of tiny bubbles as the liquid boils in its wake. The bubbles are seen as fine tracks, which show the characteristic paths of different types of particle and which are curved due to an intense applied magnetic field
